Sunwell introduced DeepChill systems to the seafood industry in 1982, and has been advancing and improving client operations and product quality ever since. DeepChill is used worldwide to cool fish species, from oily fish such as salmon, mackerel, and trout, to whitefish such as cod, hake, and tilapia.

DeepChill fully coats and seals the product, protecting it from any airborne contaminants while preventing drying of the product and ensuring a shiny appearance. The small size and non-abrasive properties of the crystals allow DeepChill to support the product and prevent surface damage and spoilage. For certain types of product, this is an essential requirement. High value finfish and shellfish processors can significantly increase yields and grade by preventing marking and physical damage to their product.
